For my money there is only one tyre worth using, and that is Schwalbe Ultremo ZX.
Trouble is, that normal price is ~£35 each, you can sometimes find them on offer.
They roll well are grippy and look nice, the other problem with them is though that the grip comes at a price, they don't actually last very long (I haven't worn a pair out yet, but then I have only done ~1000 miles on one pair.)
The Ultremo ZX are surprisingly good and comfortable for the money I paid to be honest. They roll well and they soak the vibrations well. But unlike the Continental GP4000S, it does not last as long.
I would suggest going for the GP4000S Gator Skin if you're into higher mileage and all weather riding.
